SPECIFICATION forming part of LettersPatent N o. 380,226, dated March 27', 1888. Application filed April V25, 1887. Serial No. 236,124. (No model.)

To all whom it may concern: Y l

Be it known that we, THERON SPENCER STEWART and ANNA MARIA v'ELIZABETH STEWART, citizens of the United States, re- 5 sidingrat Toledo, in the county of Lucas and State of Oh'io, have invented certain new and useful Improvements in Churn-Dashers; and

we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable Others skilled in the art to which it apper'tains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of'this speci-l iication.

Our invention relates to an improved springdasher with disk attachments, and is designed `to provide a beateror dasher that shall be adaptable to various household uses-as, for

instance, an egg-beater or as a churn-dasher.

We accomplish these objects by the mechanism illustrated in the accompanying drawings, in which like lettersl of reference indicate like parts throughout the several views.

Figure 1 is a sectional elevation. Figs. 2 and 3 are plan views illustrating the disks. Fig. 4 shows a modified form of attaching the disks and springs to the handle.

For the purpose of illustration, our device is shown in sectional elevation as employed in an egg-beater.

A designates a cylindrical vessel, preferably with slightly-inclined sides and provided with a cover, B, having an orifice in its center,

3 5 through which the handle is reciprocated, the

orifice being surrounded by a funnel-shaped guide, C, adapted to return any substance that may collect upon the handle and be caught therein back to the receptacle.

D is the handle or dasher-rod, and has attached at its lower end a helical spring or springs, in the present instance two springs, F and F, being shown, and has also two disks, E E', attached ata short distance above the rlhe disks are slightly convex, and are placed in inverse order upon thehandle or `dasherrod D, the lower disk, E', being vplaced with its concave face toward the base of the receptacle, the convex face of the disk These disks are I- perforated, as shown at I, Fig. 2, or of woven wire,'as shown at K, Fig. 3.

In Fig. 1 there are shown two helical springs, the helices being in reverse order, the disks E and E', as well as the springs F and F, being soldered to the handle D. When it is desired to construct the dasher with greater strength,

-for heavier work, as for churning, we prefer the mode of attaching shown in Fig. 4, wherein the handle is threaded, and is provided with burrs-or nuts G G G and thumb-screw H. In this construction the nut G isrst run upon the handle ,a desired distance, the disk E is placed ther'eon, and nut G run firmly against tov the disk. 'Disk E is then placed uponthe 65 y handles. Spring F is then placed thereon, its upper coils being of a diameter just sufficient to allow of its ready attachment, and nut-G is run firmly to place, thereby holding disk E and spring F firmly in position. Spring F is now similarly attached and thumb-screw -H screwed to place. By this adjustment great strength, as well as convenience in taking the parts off, if desired, Vis attained.

In operation the handle or dasher-rod D is reciprocated vertically, the springs F and Ff Opening and closing in the direction of their axis, the material to be beaten being iirst acted upon by the springs, which, being alternately closed and opened one within the other, give the initial beating, which is completed by the action of the disks. They, (the disks,) meeting the substance as it is forced through the coils, subject it to a secondary and more rigid beating, caused by the force with which it is urged through the perforations or interstices of the disks. The substance (if eggs are being beaten) is rapidly broughtto a ,thor-y oughly beaten and foamy condition, producing a greater amount in bulk and of a more 9o lasting character in its beaten state froma given amount of material than any beater ot' which we have any knowledge.

If the device is used as a churn-dash'er, the same results follow, since by the combined action of the springs and disks the sacs containing the butyric particles are more rapidly broken, leaving it only necessary to gather or assemble the particles into compactness.

vWhile we have shown two springs and two roo disks, a more or less number may be employed without departing from the spirit of our invention.

Having described our invention, what we 5 claim, and desire to secure by Letters Patent,

In a dasher, a handle or dasherrod having helical springs attached thereto, in combination with perforated convex disks attached 1o thereon in inverse order, the disks and springs being removably attached to the dasher-rod, substantially as and for the purpose set forth. In testimony that we claim the foregoing as our own we hereby affix our signatures in presence of two'witnesses.
